Dr Jonathan Foyle, architectural historian and novice climber, scales Britain's most iconic structures, from the Normans to the present day, to reveal the buildings' secrets and tell the story of British architecture and construction's development over the last 1,000 years.

Jonathan's journey takes him to the Lloyd's Building in the heart of the City of London. Built between 1978 and 1986, it is one of the finest examples of high-tech architecture in Britain and one of the great icons of London.

Aided by top climber Lucy Creamer, Jonathan abseils over 300 feet to reveal how this ultra-modern building was inspired by a Gothic castle. He scales the iconic stainless steel exterior to reveal why it is known as the Inside-Out building, and zip-lines across a sheer drop to investigate the building's humble origins as a coffee shop. He also meets Lord Rogers, one of the greatest architects of his generation and the man behind the audacious building. Show less
